Well, if you look up "trental" online, you'll find several research reports with promising results using this med to decrease side effects of radiation treatment. Specifically, "fibrosis." I suppose the theory is that the radiation from CK does cause some injury to the affected nerves, etc. Trental is believed to increase oxygenation of tissues at the microvascular level. It's also more commonly used in cases requiring a "blood thinner." It apparently changes the viscosity or slipperiness or something of your blood. Not a very scientifc explanation, I know!
Unfortunately, the stuff really caused me major stomach problems for the first three weeks, and I still have to be careful to eat and drink plenty when I take it. Also unfortunately, I've been on it for about 6 weeks, and I can't honestly say it's made any difference in energy level, balance problems, blood pressure problems. I'm still scheduled to take it for another month or so, then another followup MRI. Will keep you all posted.
